Peter Eisentraut 2f094e7ac6 SQL Property Graph Queries (SQL/PGQ)
Implementation of SQL property graph queries, according to SQL/PGQ
standard (ISO/IEC 9075-16:2023).

This adds:

- GRAPH_TABLE table function for graph pattern matching
- DDL commands CREATE/ALTER/DROP PROPERTY GRAPH
- several new system catalogs and information schema views
- psql \dG command
- pg_get_propgraphdef() function for pg_dump and psql

A property graph is a relation with a new relkind RELKIND_PROPGRAPH.
It acts like a view in many ways.  It is rewritten to a standard
relational query in the rewriter.  Access privileges act similar to a
security invoker view.  (The security definer variant is not currently
implemented.)

Starting documentation can be found in doc/src/sgml/ddl.sgml and
doc/src/sgml/queries.sgml.
